Symbol
When the “EP1_TX_0DATA” command is issued to EP1 by Command register or
Zero-Length data has been set at Endpoint-I/F, this bit will be set to 1. It will be cleared to
0 after the Zero-Length data has been transmitted.
Indicates the status of EP1_FIFO.
0y0: No valid data exists
0y1: Valid data exists
<max_pkt[10:0]>
Sets MaxPacketSize of EP1.
Set this when configuring the endpoint when Set_Configuration and Set_Interface are
received.
Set an even number for a transmit endpoint. On USB, when MaxPacketSize of a transmit
endpoint is an odd number, set an even number to max_pkt and make the odd number of
accesses to the endpoint. (For instance, set 1024 to max_pkt when the MaxPacketSize
should be 1023 bytes.)
